Problem {8} - Sort Array (bojanm)

var arr1 = [5, 4, 3, 2, 1];
var arr2 = [12, 12, 50, 2, 6, 22, 51, 712, 6, 3, 3];
function sortArray(arr) {
    var endOf = 0;
    var tempElm;
    do {
        tempElm = arr[endOf];
        for (i = endOf; i < arr.length; i++) {
            if (tempElm > arr[i]) {
                var tempValue = tempElm;
                arr[endOf] = arr[i];
                arr[i] = tempElm;
            }
        }
        endOf = endOf + 1;
    } while (endOf != arr.length - 1);
    console.log(arr)

}
sortArray(arr2);
